| Abstract:
Studies on the natural and controlled pollination of yellow passion fruit (Passiflora edulis f. flavicarpa Deg.) were in the experimental field of the College of Agriculture of Jaboticabal - São Paulo, which was constituted of 280 plants with 2 ½ years of age, planted 6.00 x 4.00 m, and sustained by a single wire, which was 2.00 m far from the soil. All flowers used in the present studied were classifiel according to style curvature and fruit set was checked 8 days after flower opering. For the natural pollination studies all flowers allowed a free visit of any kind of pollination agents. If rain happens during flowering time until 16.00 hours, there will be a decrease in fruit set as a consequence. Controlled pollination studies were done, using a screen protection. The pollination agents used were: honey bees (Apis mellifera adansonii), carpenter bees (Xylocopa Megaxylocopa frontalis (OLIVER); Xilocopa Neoxylocopa spl and Xylocopa Neoxylocopa sp2), and wind. Among the pollinations agents tested: carpenter bees were the most efficient with TC and PC flowers, SC flowers always were fruitless. Honey bees presented a low efficiency and wind pollination is nil. | |
